I model a concrete structure in which water is rising and falling and would like to create wet walls using dynamic paint (Blender 2.81). Rising and falling water are modelled by two (or more) meshes whose visibility is animated (e.g. one on - the other off, under "Object properties - Visibility"). The "water" objects are defined simultaneously as brush, the concrete parts as canvas. The problem is, that all brush objects act as brush when baking, even the non-visible ones. Is there any trick to convince Blender that only visible objects should act as a brush while invisible ones shouldn't?
EDIT: There is a workaround by replacing disappearing of an object by sudden movement out of sight and vice-versa while the object stays visible all the time.
